Rachel Clare: So lots of people have been talking about the intermittent fasting diet recently mainly because there are small studies that are showing that people do lose weight on the intermittent fasting regime.

It can work in different sorts of ways so maybe the normal five days and low calorie two days or they condense all of their meals into eight hours of the day.

The studies are often short-term and so it doesn't necessarily say that this is a sustainable way for weight loss and also in my eyes the intermittent fasting affects people's lifestyles a lot and it means that actually if they have a really nice dinner planned with their friends one day but it's the day that they're having 500 calories then what do they do?

Do they sacrifice spending time with their friends over this diet which is unlikely to be sustainable?

So people are putting their eating habits before general life and prioritizing their diets before socializing. It can even get in the way of work if somebody is not eating properly to give themselves the fuel they need to work productively.
